GENERAL DESCRIPTION

This section describes the functions, major assemblies, external
interfaces, electrical requirements and physical specifications
of the terminal.

INTRODUCTION

{

(

The CDC CC63X Multifunction Display Terminal is a microprocessorcontrolled input/output hardware device with a detached keyboard
and loadab1e 64K memory.
The basic resident terminal mode supports CYBER (Advanced) Mode
and Control Data Shared Network (CDSN) down1ine load capability. It will operate as an 1ST III terminal via the CDSN.
The major application of this terminal, however, is the versatility offered by the addition of hardware options and the capability for loading various operating programs. One of the
available options is an internal 1200/1200-baud (bit-per-second
or b/s) modem that enables terminal connection to CDSN via the
telephone lines and incorporates user oriented features such as
automatic dialing (call originate mode) and automatic answering
(answer mode).*

TERMINAL APPLICATIONS AND BUILDING BLOCKS

(

The display terminal is a versatile input/output device that can
be configured to operate in many modes by the addition of
options and any number of pluggable ROM packs. The operational
mode of the terminal is determined by the application of the
user.
The memory is loadab1e through the communications line or. an
operator plug-in memory module (ROM pack). The terminal contains internal interfaces which allow the addition of several
options, including a touchpane1 and/or an internal 1200/1200 b/s
modem. Refer to table 1-1 for display terminal features and
options.

(
(

*The automatic answering feature of the internal modem is only
available on enhanced model terminals.

Expanded Terminal Configuration
62940034 E

Since it is difficult to determine all possible display terminal
applications, this manual covers only on-site maintenance for the
display terminal in its basic and expanded configurations as
indicated in figures 1-1 and 1-2. That is, the maintenance
information contained in this manual covers the basic terminal,
the graphics board with touchpanel, and the internal modem. The
maintenance of any other hardware, software, or firmware added to
or used with the terminal is covered in their respective
maintenance manuals.
The memory of the terminal iucludes 20K bytes of ROM and 64K
bytes of RAM plus any ROM pack that may be inserted. The 20K
bytes of ROM contains the resident CYBER mode as well as programs
that perform self-testing of the terminal hardware by resident
diagnostics. The ROM pack allows a program to be loaded into the
terminal.
Operating parameters are loaded through the keyboard. The parameters are stored in a nonvolatile memory (NVM), which will
retain this information after the terminal is turned off or
unplugged (the NVM is battery-supported). The resident ROM
contains subroutines that allow qualified personnel to change the
stored parameters, when necessary.

(

CUSTOMER ENGINEERING TRAINING
In addition to providing display terminal maintenance information, this manual will also serve as the only maintenance
training document. Due to a low piece-part count, internal
diagnostics and modular construction, there is no display terminal classroom instruction offered. By reading and using this
manual, the CE will acquire the expertise to isolate display
terminal malfunctions. Section 6 lists the main tasks a CE must
be able to perform before responding to a customer request for
maintenance on the terminal.
The CC63X display terminal training course consists of reading
this manual and taking a final test found on Engineering Services Educations PLM. This test covers the following objectives:

(
(

•

Locate and list the function of all major assemblies,
components and controls.

•

List the steps necessary to initiate, execute and terminate the resident diagnostic tests.

•

List the field-replaceable units (as specified by the SAM
listings) for terminal malfunctions.

THEORY OF OPERATION

GENERAL
The operational mode of the display terminal is determined by
parameters set in from the keyboard. Parameters may be selected
to initiate the resident CYBER mode, or to load and initiate host
programs. The terminal contains firmware for the resident CYBER
mode~ any other program must be downline-loaded from the host.
The terminal also contains firmware for self tests and for
loading host controlware.
Operations within the terminal are controlled by a microprocessor.
It can interface asynchronously with a higher-level
processor either directly or through a modem. The terminal is
multifunctional with the base unit being an alphanumeric
display.
It contains interfaces for three small option boards
and two large option boards. These boards provide interfaces to
host computers, modems, and peripheral equipment.
Refer to
figure 4-1 for a block diagram of the display terminal.

(

•

The operator uses the keyboard to enter, change, or delete
information and to select initial operating parameters. The
terminal is multifunctional, having the capability for one
standard and six foreign languages and a variety of graphics
symbols. Terminal-operating parameters are entered from the
keyboard into a nonvolatile RAM, and read by the microprocessor~
There are three groups of operating parameters:
•

Terminal installation parameters (select terminal-related
conditions, such as interfaces, memory option, or type of
peripheral to be used).

•

Mode installation parameters (s.elects port rates and data
rates of each operating mode, such as CYBER).

•

Mode operator parameters (determines conditions within
which selected mode will operate, i.e., on line, off
line, 80/132, cursor type, alert, etc.) •

The terminal uses a Z80B microprocessor which controls all
operations inside the terminal.
It directs the operations of
associated peripherals such as printers and modems. The microprocessor uses 64K of dynamic RAM for instruction processing.
This RAM is dedicated for program operations and CRT refresh.

(

An internal ROM (figure 4-1) contains the resident CYBER mode,
resident diagnostics, and controlware loaders. The diagnostics
consist of self tests which are performed each time the terminal
is activated for use.
(POWER on or RESET.)
The nonvolatile memory (NVM) is a RAM device which stores
keyboard-entered operating parameters for a selected operation.
A battery maintains the stored data when terminal power is
removed.
If terminal power is ever turned off and the battery
removed, default parameters are forced into the nonvolatile
memory (default parameters are described in the manuals listed in
the preface).
The pluggable memory module (ROM pack) is optional and can be
used in a number of special operations. The terminal can
checksum the ROM pack contents, and load operating firmware from
the memory module.

MAJOR ASSEMBLIES
Figure 4-2 depicts the major assemblies comprising the display
terminal and the following paragraphs describe those assemblies.

(
DISPLAY MONITOR

{

The display monitor consists of a cathode-ray tube (CRT) with
yoke and a CRT monitor board. The CRT screen provides a display
of alphanumeric and graphic symbols. A green phosphor screen and
reduced-glare faceplate is used. The screen measures 380 mm (15
inches) diagonally with a 203 mm (8 inch) by 262 mm (10.3 inch)
viewable area.
The CRT monitor board contains the horizontal and vertical
deflection circuits, video circuits, and the high voltage power
supply. These circuits are responsible for generating and
deflecting the electronic beam in the CRT/yoke assembly. The
video signal unblanks (illuminates) the screen dots at the proper
times to present readable information. Vertical and horizontal
sync pulses ensure a stable trace. The sync pulses and video
signal originate on the main logic board.

(
(

Directly below the CRT are the operator controls.
Section 2 for a description of these controls.

62940034 E

Refer to

4-3

KEYBOARD
The detached keyboard provides for operator entry of symbols and
control codes. Each key, when depressed, sends an 8-bit serial
code and parity to the keyboards universal asynchronous
receiver/transmitter (UART). A similar code is sent when the
key is released. This allows the terminal program to monitor
the state of the keyboard and assign and/or define a resultant
activity. There are 104 keystations. Keyboard arrays are
available to support foreign language transmission. When using
a foreign language, the keyboard is modified by installing
selected keycaps. The keyboard contains an adjustable leg for
selecting one of two operating positions. There are three
keyboard modes, shift, lock, and control. These modes are
controlled by the terminal. The installation parameters allow
the selection of character generation to match the key-cap set.

(LOGIC DRAWER ASSEMBLY

(

The logic drawer assembly consists of a removable rack on which
the main logic assembly board, power supply board, memory
module, small option boards (if any), and the large option
boards (if used) are mounted. The logic drawer assembly
contains an internal plug-in board for mounting the small option
boards (if used). The rear of the logic drawer assembly forms
the backpanel of the terminal. The backpanel contains
input/output connectors (I/F 1 through I/F 5), switches, circuit
breaker, and the terminal power cord. A battery is mounted in
an enclosure accessible from the backpanel. (The battery is used
to retain stored parameters in the event of power loss.)
•

Main Logic Board - The main logic board is a large
printed circuit board containing most of the display
terminal logic.
It contains a microprocessor that
provides control of display operations as determined by
preselected installation parameters. The main logic
board also contains counters, control logic, ROMS, RAMS,
UARTS, and external interfaces.
It interfaces the CRT
monitor, and installed option boards through a flat
ribbon cable.

•

Power Supply Board - The switcher power supply provides
fully regulated dc power with minimal power loss. It
supplies +5, +12, -12, and +24 V dc power.

•

Large Option Boards - These options, if installed, enable
additional functions of the terminal. Currently available large option boards include the dot-graphics board
and the internal 1200/1200 b/s modem board (refer to
figure 4-2).

(

(

(

ENCLOSURE
All the internal parts of the terminal are housed in the
enclosure or hood. The enclosure (figure 4-2) attaches to the
CRT bezel adapter assembly, which contains the CRT, yoke, and
CRT monitor board. The bezel assembly is attached to the
CRT/bezel adapter assembly.
If the graphics option is installed
the touchpanel is mounted in back of the bezel assembly.

The internal and external interfaces used in the terminal connect
to the main logic board as shown in figure 4-3. The terminal may
be connected to a host either through the RS232-C interface (connector Jl) or through the internal modem interface (I/F-4 slot).
The main bus interface (connector J4) can accommodate up to three
small option modules and two large option modules. A small
option mother board (internal to the terminal) provides a fanout
of the bus to accommodate the three small options. These small
options plug into IIF 1, IIF 2, and IIF 3 slots in the rear of
the terminal (connect to mother-board J2, J3, and J4 connectors
respectively). If installed, the memory module connects to main
logic board connector J3.
The main logic board connectors J2,
J5, J6 and J8 contain internal interfaces. A diagram of these
interfaces is shown in figure 5-1.

5. Position the terminal so that it rests on the rear frame
with the glass screen facing upward.
6. Remove the four screws securing the bezel adapter
assembly to the hood (figure 6B-7). Early units were
built with two short screws at the top and two longer
screws at the bottom, discard the two shorter screws (if
applicable) as two longer screws are provided with the
replacement bezel adapter assembly.
7. Remove the assembly from the display terminal hood and
set it face (screen side) down.
NOTE
The power actuator bar should fall
loose inside hood. Remove the bar
together with small return spring
located at rear of bar. Set the bar
and spring aside for reassembly
later. The drawer track might now be
loose inside the enclosure, or still
in place on the bezel adapter assembly.

NOTE
When replacing bezel adapter assembly,
check surface noted on figure 6B-7.
If surface is recessed at corners
where touchpanel or anti-glare panel
~ttaches, look at detail on figure
6B-4 showing top of frame where power
supply is attached. Compare this to
terminal and remove cross hatched area
with a file or clipper, if needed.
This will prevent frame from wedging
up against CRT when installing bezel
adapter assembly.
8. To reinstall, after removing the plastic bag (taped to
the bezel adapter assembly) containing the replacement
screws fit the bezel adapter assembly in place.
Install
the two top screws (using the replacement screws) that
secure the bezel assembly to the hood, but do not
compress the washers.
9. Lift terminal up and place it on its pedestal.
10. Insert the power actuator bar from the rear of the

KEYSTATION CODE ASSIGNMENTS

The basic keyboard consists of 106 keyswitches or keystations
(figure A-I). Each keyswitch outputs a code when the switch is
pressed and when it is released. The code is unique to the
keyboard and is not an ASCII code. These codes can be displayed
during the resident diagnostic TEST 3 keyboard test. Table A-I
lists the codes for all keystations.

Figure A-I.

Keystation Assignments

On some keyboards, a keycap will cover more than one switch. In
this case the code for both is generated (figure A-2) when the
keycap is pressed (the last received is shown).

RASTER DRIFT

B

The CC63X display terminal has a terminal installation parameter
that allows the installer or operator to move the raster left or
right and/or up or down. This allows for correction of raster
drift due to CRT aging. At the factory, the parameter values are
set at zero (no displacement) before the vertical and horizontal
centering alignments are made to the monitor board. As the CRT
ages, the customer or operator can use this parameter to center a
raster that has started to drift.

(

Before any monitor board adjustments are made in the field, the
parameter values or displacement values must be set at zero.
Proceed as follows to check the present parameter values and zero
if necessary.
1. Power on the terminal (procedure 1), if not already power
on.
2. Pullout the TEST switch.
3. Press RESET switch (initiate TESTl).

(

4. When the MODE SELECTION MENU appears on the screen, push
the TEST switch in.

Press CTRL and SETUP keys. This will display terminal
installation parameters.
